Vely is a tool for writing web and command-line applications in C. Vely combines high performance and the low footprint associated with C programming with ease of use and improved safety reminiscent of languages like PHP. It's free and open source software, and licensed under GPLv3 and LGPL 3 for libraries, so you can even build commercial software with it.

Last week, e-con Systems launched the DepthVista camera which contains both an RGB and a Time of Flight (ToF) depth camera with a range of up to six meters. According to the company, the DepthVista can measure the distance from itself to a target object with an accuracy of < 1% depending on environmental conditions.

You’re in the news. But not with the headline you want. You’re not getting attention because of your choice of text editor or the number of spaces you use to indent code blocks. However motivating those preferences are for you and me, the non-technical world sees them as private choices. You find your code in the headlines for a different and unpleasant reason: open source dependency management.

Linux laptop player System76 is joining forces with HP to release a high-powered Pop!_OS-powered developer laptop.

In the age of high-speed internet, most large information systems are structured as distributed systems with components running on different machines. The performance of these systems is generally assessed by their throughput and response time. When performance is poor, debugging these systems is challenging due to the complex interactions between different subcomponents and the possibility of the problem occurring at various places along the communication path.

Kubernetes Database Operator is useful for building scalable database servers as a database (DB) cluster. But because you have to create new artifacts expressed as YAML files, migrating existing databases to Kubernetes requires a lot of manual effort. This article introduces a new open source tool named Konveyor Tackle-DiVA-DOA (Data-intensive Validity Analyzer-Database Operator Adaptation). It automatically generates deployment-ready artifacts for database operator migration. And it does that through datacentric code analysis.

A long lost native Unix version of the killer PC spreadsheet has not only been rediscovered, but almost unbelievably, it's been updated to create a native Linux version.

In this document, we will be taking a look at the fundamentals of VirtIO from a technical standpoint as well as a deep dive into some of its key areas. This introduction to VirtIO is written assuming the reader has little to no working knowledge of VirtIO, but should also be a helpful refresher to those who are already familiar.

The next release of Ubuntu, version 22.10 and codenamed Kinetic Kudu, will switch audio servers to the relatively new PipeWire. Don't panic. As J M Barrie said: "All of this has happened before, and it will all happen again." Fedora switched to PipeWire in version 34, over a year ago now. Users who aren't pro-level creators or editors of sound and music on Ubuntu may not notice the planned change.

In this article, we will see how to use Lifecycle Manager to automate the creation, retention, and deletion of snapshots taken to back up our Amazon EBS volumes. This automation helps us to protect valuable data by enforcing a regular backup, retain backups, reduce storage costs by deleting older backups.

When operating on the Linux command line, it is easy to get disoriented, which can have disastrous consequences. I once issued a remove command before realizing that I'd moved the boot directory of my computer. I learned to use the pwd command to know exactly which part of the file system I was in (and these days, there are command projects, like trashy and trash-cli, that serve as intermediates when removing files).

AMD launched the Kria KR260 Robotics Starter Kit which is built around the Kria K26 Zynq UltraScale+ XCK26 System-on-Module (SoM) that entered the market last year. The KR260 has similar specs as the Kria KV260, however, the former is optimized for industrial applications instead of vision AI applications.

Crane Venture Partners offers a different kind of VC that is laser-focused on helping open source developers get the funding they need to turn their itch into a scratch and then a business.

Many organizations have security policies in place that dictate how to store sensitive information. When you're developing applications for the cloud, you're probably expected to follow those policies, and to do that you often have to externalize your data storage. Kubernetes has a built-in system to access external secrets, and learning to use that is key to a safe cloud-native app.

Fail2ban is free and open-source IPS (Intrusion Prevention Software) that helps administrators secure Linux servers against malicious login and brute-force attacks. In this tutorial, we will show you how to install and configure Fail2ban for securing the Ubuntu 22.04 server. This guide also covers the basic command of fail2ban-client for managing Fail2ban service and jails.

Version 251 of the controversial systemd Linux init system is here, and you can expect it to feature in the next version of your preferred distro. The unified system and service manager for Linux continues to grow and develop, as does Linux itself. There is a comprehensive changelog on Github, so we will just try to pick out a few of the highlights.

In this first part of our Complete Guide to Keylogging in Linux, we will explore the basics of keylogging and its importance in the realm of Linux security, and dive deeper into keylogging in userspace, demonstrating how a keylogger can be written for Linux, by reading events directly from a keyboard device.

Sfera Labs released the Exo Sense RP which is a compact module that combines sensors to monitor air quality, humidity, temperature, light, motion and audio sensing. Unlike the SENSE board by Nexus Electronics and presented by LinuxGizmos a few days ago, the Exo Sense RP integrates a Raspberry Pi RP2040 IC.

What advice would you give a new Linux user? We asked our community of writers to share their favorite Linux advice.

Understand the key concepts behind images and containers. Then try a lab that demonstrates building and running images and containers.
